	Sohagpur Coalfield is a part of Central India Coalfields. The latter is spread over the districts of [[Surguja district\|Surguja]], [[Koriya district\|Koriya]] (both in Chhattisgarh), [[Shahdol district\|Shahdol]] and [[Umaria district\|Umaria]] (both in Madhya Pradesh). There are fourteen coalfields in this group, namely Korar, Umaria, Johilla, Sohagpur, Sonhat, Jhilimili, Chirimiri, Sendurgarh, Koreagarh, Damhamunda, Panchbahini, Hasdeo-Arand, Lakhanpur and Bishrampur. The group covers an area of about {{convert\|5345\|km2}} with estimated reserves of 15,613.98 million tonnes. The deposits are at a depth of 0–1200 meters. Therefore, extraction is mainly amenable to underground mining except a few blocks in eastern part of these coalfields which have opencast potential.<ref>{{cite web \| url = http://secl.gov.in/ \| title = Central India Coalfields \| last = \| first = \| work = Coalfields \| publisher = South Eastern Coalfields Ltd \| accessdate = 2011-09-03 \| archive-url = https://web.archive.org/web/20110902005800/http://secl.gov.in/ \| archive-date = 2011-09-02 \| url-status = dead }}</ref>		Sohagpur Coalfield is a part of Central India Coalfields.

	There are four coal seams, about 1–4 m in thickness spread across three sub-basins: Burhar-Amlai sub-basin located in the western part of the coalfield, Kotma sub-basin, located on the Anuppur-Chirimiri branch line, 40 miles east of Burhar and the Jhagrakhand-Bijuri sub-basin in the easternmost part of the coalfield.<ref name=sharma/> In general the coal is of [[coal rank\|low rank]], high moisture, high volatiles and non-coking type.<ref name=admin/>		There are four coal seams, about 1–4 m in thickness spread across three sub-basins: Burhar-Amlai sub-basin located in the western part of the coalfield, Kotma sub-basin, located on the Anuppur-Chirimiri branch line, 40 miles east of Burhar and the Jhagrakhand-Bijuri sub-basin in the easternmost part of the coalfield.<ref name=sharma/> In general the coal is of [[coal rank\|low rank]], high moisture, high volatiles and non-coking type.<ref name=admin/>

'''Sohagpur Coalfield''' is located in [[Shahdol district]] in the [[India]]n [[States and territories of India|state]] of [[Madhya Pradesh]] in the basin of the [[Son River]]. It is the biggest coalfield in the state of [[Madhya Pradesh]].

==History==
Coal was discovered in this region, first in Sohagpur Coalfield by a British geologist named Franklin in 1830.<ref name=sharma>Sri Kamal Sharma, Resource Development in Tribal India: an Example of the Baghelkhand Plateau, p. 161, 164, Northern Book Center, {{ISBN|81-85119-57-0}}</ref> After the [[World War I|First World War]], the first attempts at coal mining failed, but around 1926 Burhar and Dhanpuri collieries were started. The Anuppur-Chirimiri line was opened in 1939 and mining operations were extended subsequently.<ref name=sharma/> Sohagpur Coalfield is a remnant in the [[Son River|Son]] basin of Gondwana deposition.<ref>{{cite journal |title = Petrographic, chemical and trace-elemental composition of the coal of Sohagpur coalfield, Madhya Pradesh, India | doi = 10.1016/0166-5162(87)90045-0|volume=9 |issue = 2 |journal=International Journal of Coal Geology |pages=187–207|year = 1987 |last1 = Pareek |first1 = H.S. }}</ref>
